SAJJAD KHAKSARI
Education Management Information System (EMIS) in Iran, is the bachelor degree thesis and the final dissertation of Sajjad Khaksari in Industrial Engineering [Analyze and Planning Systems] course from Tehran North University in 2007. The Iranian Education Administration system and Non-Governmental Organizations (NGO) of Iranian teachers unions were major case studies of the "EMIS In Iran".
Sajjad’s essay has censored rigorously and the library of “Tehran North Engineering University Branch” refused to receive a copy of his thesis because of its significant critical results against Iranian regime Education Administration Policies.

Numerous stochastic models for repairable systems have been developed by assuming different time trends, and re- pair effects. In this paper, a new general repair model based on the repair history is presented. Unlike the existing models, the closed- form solutions of the reliability metrics can be derived analytically by solving a set of differential equations. Consequently, the con- fidence bounds of these metrics can be easily estimated. The pro- posed model, as well as the estimation approach, overcomes the drawbacks of the existing models. The practical use of the proposed model is demonstrated by a much-discussed set of data. …
Ranking Maintenance Strategies From The Point Of View Of Lean Thinking: Group Decision Making Model By Using Borda Method, Mehdi Jafarian, Kamran Shahanaghi, Aliakbar Faegh, Majid Samsami

The selection of maintenance strategies is a typical multiple criteria decision-making (MCDM) problem. There have been taken different maintenance strategies in order to obtaining optimistic maintenance strategy. In this paper we aim to rank different maintenance strategies from the point of view of lean thinking. After obtaining information from experts whose expertness is in field of maintenance, in order to ranking these strategies we form a group decision making model and solve this model by using Borda method. Finally we analyze its results

در فضای رقابتی امروز، بنگاههای اقتصادی در تلاشی مستمر برای دستیابی به کیفیت بالا، هزینه پایین، افزایش سرعت در ارائه کالا و خدمات و ... میباشند. بنابراین دستیابی به اهداف فوق را میتوان در زمره مهمترین دغدغههای مدیران امروزی قلمداد نمود. نگهداری و تعمیرات نیز به عنوان یکی از مهمترین فرآیندهای یک بنگاه اقتصادی از این قاعده مستثنا نبوده و در زیر ذره بین مدیران و کارشناسان قرار گرفته است. در این مقاله سعی نویسندگان بر این بوده است تا برخی از مهمترین جنبههای پژوهشی مطرح در این حوزه را عنوان نمایند.

In this paper, modeling and solving of a single machine scheduling problem with a single flexible maintenance activity and stochastic maintenance activities time was considered. Also it assumes that the all activities are resumable. Chen solved and investigate complexity of this problem without probabilistic condition by Mixed binary integer programming (BIP) so we solving this problem with considering stochastic programming concepts. An example has investigated at the end chapter to show actual consequences by Lingo.

The last step of a condition based maintenance (CBM) program is maintenance decision-making. This step is the most important and the most critical stage of maintenance for executive personnel and management whom work on taking maintenance actions. This decision making would be done according to certain criteria such as risk, cost, reliability and availability. This paper considered a dynamic programming model to optimization of the threshold for the preventive maintenance actions in a condition-based maintenance program. The basis of this modeling is the average cost of maintenance actions, failures and exchanges. In this paper, we improved the memory of the …

فعالیت های نگهداری و تعمیرات در هر بنگاه اقتصادی از یک سو سبب کاهش هزینه های ناشی از عدم فعالیت دستگاه ها، هزینه های تعمیرات و سود از دست رفته، شده و از سوی دیگر به عنوان فعالیتی هزینه بر، هزینه های گاها سنگینی را به سازمان وارد می¬سازد. از این رو توسعه سیاست های نگهداری و تعمیرات و بهینه سازی هر یک از این سیاست ها، عاملی مهم در کاهش هزینه های سازمان خواهد بود. در این میان فرآیند نگهداری و تعمیرات مبتنی بر شرایط، به عنوان یکی از کاراترین سیاست¬های نگهداری و تعمیرات، با حذف فعالیت های نگهداری …
